Basic Differential Equation

Hey, I'm not sure how to start this problem, as the ODE does not seem to be seperable. (We have only had 1 lecture on seperable equations / exponential models).

I feel blind.

Verify that the function is a solution of the Initial Value Problem .

I think that I need to seperate the equation to the form and integrate, but I cannot figure out how to obtain that. Once I do, I think we sub in into the integrated equation and hit to show that the result is .
